Abstract

To locally heat only a trim edge. A processing method includes: punching a steel plate; and heating an end face of a heating coil by disposing the heating coil in a non-contact manner along an end surface of a trim edge of the steel plate formed in the punching and perpendicular to a plate thickness direction of the steel plate and applying a current through the heating coil to cause an induced electromotive force on the steel plate. The heating coil is configured by winding a coil wire spirally at least one time.
